IMPROVEMENT IN GRAIN-DISTRIVBUTERS-FOR SEED-DRILLS.

Specication forming part of Letters Patent No. 169,813, dated November9, 1875 application led I June 17, 1875.

To all whom it may concern:

Be it known that I, CHARLES F. JOHNSON, Jr., oi' Owego, in the county ofTioga and State of New York, have invented certain new and usefulImprovements in Seed-Distributers for Grain-Drills; and I do herebydeclare the following to be a full, clear, and exact description of thesame, reference being had to the accompanying drawings, making Myinvention relates to a seed-distributer for grain-drills, in which aVone-part wheel, having a high, dish-like ange and a fluted huh, isincased in and adapted to a two-part shell or casing, so that threecastings or pieces constitute the whole d-istributer, thus making itvery simple, easily cast, and readily iitted and applied to aseed-drill, as will be explained.

To enable others skilled the art to make and use my invention, I willproceed to de scribe the same with reference to the drawings. Y

The seed-wheel A is of a bowl or dish form, having a iiange, ct, ahub,b, a shaft-opening, c, a recessed or concave back, d, and eccentricflutings e, wrought and cast upon or with it, and constituting but onesingle piece. AOne of the shells or casings-nainely. B-is cast with aflange, ff', by which it is secured to the seed-box D, an auxiliaryhopper, g, an opening, h, for the hub of the seedfwheel to projectthrough, a flange or curb, t', and onehal-t, j, ofthe spout, into whichthe grain drops from the seed-wheel, and from whence it is carried by atube, in the usual way, to the shoe and into the ground.

The other shell or. casing, C, is made and cast with a portion, k, thatforms one of the sides of the auxiliary or secondary hopper g, an opening, l, somewhat less in diameter than the 'extreme diameter of theseed-wheel, and

the remaining portion m, Which, when the two parts are put together,completes the spout, into which the grain falls from the seed-wheel,

and is conducted into the ground, as above stated. The shell or casing Ois united to the oasin gs B by bolts passing through the open- Y to theperimeter 4oi' the flange, so that that part of the seed-wheel acts as astirrer to prevent the grain from bridging or clogging in the throat ofthe secondary hopper g.

The grain carried around by the flutingsof the seed-wheel must pass tothe end of the curb i before it can drop, and when it reaches that pointit falls int-o the spout, whence it is carried to the ground in theusual Way.

On the rear oi the casing is made an opening, p, into which a fertilizerfrom another box or hopper on the machine may be introduced, and,mingling with the grain after it has passed the seed-wheel, be carriedto the ground with it, and deposited there.

A square shaft, driven from the ground wheel or wheels of theseed-drill, may pass through the square openings c of the seedwheels, ofwhich there lnay be a series, coilnected with the hopper in the usualwell-V known way.

Having thus fully described my invention, what 1 claim is- In aseeddistributer for grain-drills, the combination oftheseed-distributing wheel A, with its iiutings e, and a ilange, a,extending high up into the auxiliary hopper g, with the casings B O, forforming a support for the Wheel, and, with said wheel, constituting theauxiliary hopper above, and the curb t, and

terminatin g in a seed-conductor below, as and for the purpose describedand represented.
